题记------学习别人的精髓,并加以总结,消化吸收,这就是提高!!!
DailyRollingFileAppender生成的文件是不带时间戳的,必须在某个时间点后,才对原来文件加上时间戳进行重命名,这样就有很大的问题,当天的日志,没有时间戳,而且如果在log4j.properties配置文件路径采用log4j.appender.dailyFile.File=E:/logs/log_或者log4j.appender.dailyFile.File=${webapp.root}/WEB-INF/logs/log_这种命名方式的,那么恭喜你,你生成的日志文件连后缀名都没有,想打开还得自己加后缀名,比如.log,.xml什么的总之很不方便。在此处说句题外话,就是解释下什么是${webapp.root},这个说简单点就是你项目运行环境的绝对路径,一般在web.xml中如果我们不配置webAppRootKey默认的缺省值就是${webapp.root},不过本人还是建议大家配置一下webAppRootKey,这样在同一服务器下运行多个项目就没冲突了。
log4j真的是一款很强大的日志开源框架,免费且好用,当然也会略有瑕疵,如果项目允许,我建议小伙伴们还是采用logback框架吧,这个框架不仅效率高,而且还规避了本文谈及的一系列问题,更关键的是如果你会用log4j那么学会使用logback简直是小kiss,废话不多说,这次主要是重新了log4j的两个类,FileAppender及其子类DailyRollingFileAppender,由于篇幅太多我就不一一赘述代码改动了,同志们如果想知道改了哪些,可以采用代码比对工具Beyond Compare 4,下载地址http://download.csdn.net/download/gongxun344/9982938,附apache-log4j-1.2.17源码地址http://download.csdn.net/download/gongxun344/9982916。话不多说,上本人修改后的源码:
